Page Fault Liberation Army
Explore the hidden computational power of x86 processors' Memory Management Units (MMUs) in this Hack In The Box Security Conference talk. Delve into the intricate world of memory translation logic, data tables, and trap mechanisms that are often overlooked in modern operating systems. Discover how the MMU can be programmed as a Turing-complete processor and learn about tools that unleash its potential. Examine design suggestions and possible FPGA prototypes for enhancing the virtual memory system as a runtime policy enforcer. Follow the presenters through topics such as ELF metadata, finite state automata, segmentation, page tables, trap handling, and task switching. Gain insights into the concept of "weird machines" and their implications for security research and policy enforcement.
